In-depth introduction to Redis-redis sentinel cluster, simple introduction to redis-redis1. Sentinel Sentinel is a Redis high availability solution: a Sentinel system consisting of one or more Sentinel instances can monitor any number of Master servers, and all slave servers under the master server. When the monitored

200 Redis instances on a server, and it crashes. The only way to do this is to make different types of data belong to different applications and separate from each other.So, is there a way for Redis to keep different application data separate from each other and stored on the same instance? is equivalent to the MySQL database, different application data is stored under different databases.Under

In-depth introduction to the Redis-redis underlying data structure (below), simple introduction to redis-redisOverview: 　　　　Learning to use Redis doesn't actually need to study the implementation of its underlying data. We only need to know which common data types he has, and then use them skillfully, so that we can ha

introduction of distributed characteristics of Redis Sentinel Redis Sentinel is a distributed system that is designed to operate in an environment where many sentinel processes cooperate with one another. The advantages of having many sentinel processes cooperating with each other are as follows: When multiple Sentinel agree that a master is no longer available, fault detection is performed. This significan

process.1 indicates that the kernel allows all physical memory allocation regardless of the current memory status.2. indicates that the kernel is allowed to allocate more memory than the total physical memory and swap space.Redis generates a sub-process when dumping data. In theory, the memory occupied by the child process is the same as that of the parent. For example, the parent occupies 8 GB of memory, at this time, 8 GB of memory should also be allocated to the child. If the memory is not e
